Figure 3 is arsidevview with the capyout of gear or thrown open.

Figure-4 is atop view of cap, or my improvement.

This instrument or improvement is constructed of' castor wrought iron, or other metal.

To enable others to make and use my invention or improvement, I will proceed to describe its construction or-operation. v l Y I construct my improved cultivzttor-too'th of cast iron, but thesa'me lmay be -mile of any of the baser metals. An'orrlinnry cultivatorJtooth .is constructedivith a. thittened'neck, as represented in gs. l and 3, letter e. Over the neck I place a. cast-iron cap, as represented by letter A in all the figures, 1,'2, and 4. The cap is fastened to the neck by the hin-geAorhscrevv-bolt, represented by letter a in figs. l, 2, and 3,1and' the wooden pin or'key represented in tig. 2, letter c, the same to be attochedto' the beam 'of the=cultivator by bolt passing through a. hole in the capv at letter d. vLetter b. in all the figures, represents-n. steadyng-tip or' teat ontop of the cap. The cap being attached to thel wooden bea-1n, -and the tooth attached -to the cap, should` the tooth come in contact'with 'a'hard or unyieldi-ng substance, the wooden pin vor key atc will break and save the tooth. l What I claim as my invention or improvement, and desire to secure -byLetters Patent, is-
